@halloween girl -- Im a huge fan and user of LockNLock, but the best product for produce is called "Prepworks by Progressive Prokeeper."
You get them on Amazon. They are similar to LockNLock, but they have vents on the side, and trays on the bottom to whisk away or keep water depending on the type of produce. They are FANTASTIC!! Pricing is not extreme and well worth the investment.
I have never been able to keep produce fresh until I got the Prepworks containers. You'll be amazed how long fruit & veggies last. Highly recommend!!
